After carrying out the calculation, a circularly modeled opening appears as a quadrilateral.
How is it possible to fix this problem?


The consideration of curved elements depends on the FE mesh refinement.
An FE element always has straight outer edges.
If the FE mesh is selected too roughly, the result is a very inaccurate mapping of the curved elements with straight lines.
If the global setting of the target length of the finite elements is specified with sufficient accuracy in 'Calculation' → 'FE Mesh Settings', you can also perform a local FE mesh refinement on the nodes, lines, or surfaces.
